How to solve real number arithmetic
Answer/Step-by-step explanation
1. When adding real numbers with the same sign the sum will have the same sign as the numbers added.
2. When adding real numbers with different signs you subtract the lesser absolute value from the greater one. The sum will then have the same sign as the number with the greater absolute value.
3. There are a couple of properties of addition:
The additive commutative property tells us that the order in which you add the numbers does not change the sum.
4. And the additive associative property tells us that it also that the order in which we group three or more numbers does not affect the sum.
5. The additive identity property tells us that the sum of a number and 0 is always the number.
6. And the additive inverse property tells us that if you add a number with its opposite you will always get 0

Find the mean absolute deviation of 5,9,7,0,3,5,5
Answer: 1.92
Step-by-step explanation:
Formula to find the mean absolute deviation:
[tex]MAD =\sum^{n=i}_{n=1}\dfrac{|x_i-\overlien{x}|}{n}[/tex]
, where [tex]\overline{x}=[/tex] mean , [tex]x_i's[/tex] = data values, n= number of data values.
Given data: 5,9,7,0,3,5,5
n= 7
Mean:
[tex]\overline{x}=\dfrac{5+9+7+0+3+5+5}{7}\\\\=\dfrac{34}{7}[/tex]
MAD = [tex]\dfrac {|5-\dfrac{34}{7}|+|9-\dfrac{34}{7}|+|7-\frac{34}{7}|+|0-\dfrac{34}{7}|+|3-\dfrac{34}{7}|+|5-\dfrac{34}{7}|+|5-\dfrac{34}{7}|}{7}[/tex]
[tex]=\dfrac{\frac17+\frac{29}{7}+\frac{15}{7}+\frac{34}{7}+\dfrac{13}{7}+\frac17+\frac17}{7}\\\\=\dfrac{\frac{94}{7}}{7}\\\\=\dfrac{94}{49}\approx1.92[/tex]
Hence, the mean absolute deviation of 5,9,7,0,3,5,5 is 1.92(approx)

Given m||n, find the value of x.
+
(7x-7)°
m
(6x+11)°
Answer:
x = 18
Step-by-step explanation:
[tex](7x - 7) \degree = (6x + 11) \degree \\ (exterior \: alternate \: \angle s) \\ \\ 7x - 7 = 6x + 11 \\ \\ 7x - 6x = 11 + 7 \\ \\ x = 18[/tex]
what is x equal to ? 7x+3=2x-4
[tex]7x +3 = 2x - 4 \\ 7x - 2x = - 4 - 3 \\ 5x = - 7 \\ x = \frac{ - 7}{5} \longrightarrow - \frac{7}{5} [/tex]
Answer Check by substituting the value of x in the equation.[tex]7 ( - \frac{7}{5} )+ 3 = 2( - \frac{7}{5} ) - 4 \\ - \frac{49}{5} + 3 = - \frac{14}{5} - 4 \\ - \frac{49}{5} + \frac{15}{5} = - \frac{14}{5} - \frac{20}{5} \\ - \frac{34}{5} = - \frac{34}{5} [/tex]
The equation is true for the value of x. Therefore the answer is x = -7/5
Answer[tex] \large \boxed{x = - \frac{7}{5} }[/tex]

The graph represents Jason’s trip on the bus, showing his distance from home as a function of time. Select all statements that are true based on the graph.
A. The bus is traveling at a decreasing speed.
B. The bus traveled a total distance of 310 miles.
C. The bus traveled at a faster speed during the first 4 hours of the trip.
D.After traveling 200 miles, the bus trip has more than 3 hours remaining.
E. The bus traveled a total distance of 130 miles in the first 4 hours of the trip.
F. During the first part of the trip, the bus traveled at a constant speed of 45 miles per hour.
Answer:
A , E, F
Step-by-step explanation:
Three statements are true based on the graph the correct options are D, E,F
How to find the speed of an object?If the object is going linearly, and at a constant speed, then the speed of that object is given by the distance it traveled to the time it took to travel that distance.
If the object traveled D distance in T units of time, then that object's speed is
[tex]Speed = S = \dfrac{\: Distance \: traveled}{\: Time \: taken} = \dfrac{D}{T} \: \rm unit \: length/unit \: time[/tex]
For option D, we can see in the graph the bus has completed 200 miles of distance between the 2nd and 3rd hour. So, there are more than 3hours remaining, and option D is correct
For option E, it is clear from the graph that after 4 hours the distance traveled by the bus is 130miles
For option F; the distance traveled in first 4 hours= total distance from home - remaining distance after 4 hours
310-130=180miles
time= 4hours
speed=distance/time
speed= 180/4= 45miles per hour
hence, D, E,F are true

Answer:
number 7:Sometimes We can have two acute angles, 20 and 30, 20+30=50, which is still acute, We can have two acute angles, 45 and 45, 45+45=90, which is neither acute nor obtuse. We can have two acute angles, 80 and 80, 80+80=160, which is obtuse.acute angles are less than 90 degrees. However, they can sometimes equal obtuse angles. For example, two acute angles measures of 70 degrees and 30 degrees are both acute. Add them together they equal 100 degrees, which is obtuse. some examples: 40° and 30° are acute angles 40° + 30° = 70°, which is an acute angle 60° and 30° are acute angles 60° + 30° = 90°, which is a right angle 50° and 70° are acute angles 50° + 70° = 120°, which is an obtuse angle.
number 8 :Since the intercepted arc LN is the diameter of the circle, its measure is 180 degrees, so m<LMN = 90
Conclusion: the sum of two acute angles is sometimes an acute angle.

Step-by-step explanation:
Given the inequality
-2x < 10
-6 < -2x
Part a) Is x = 0 a solution to both inequalities
FOR -2x < 10
substituting x = 0 in -2x < 10
-2x < 10
-3(0) < 10
0 < 10
TRUE!
Thus, x = 0 satisfies the inequality -2x < 10.
∴ x = 0 is the solution to the inequality -2x < 10.
FOR -6 < -2x
substituting x = 0 in -6 < -2x
-6 < -2x
-6 < -2(0)
-6 < 0
TRUE!
Thus, x = 0 satisfies the inequality -6 < -2x
∴ x = 0 is the solution to the inequality -6 < -2x
Conclusion:
x = 0 is a solution to both inequalites.
Part b) Is x = 4 a solution to both inequalities
FOR -2x < 10
substituting x = 4 in -2x < 10
-2x < 10
-3(4) < 10
-12 < 10
TRUE!
Thus, x = 4 satisfies the inequality -2x < 10.
∴ x = 4 is the solution to the inequality -2x < 10.
FOR -6 < -2x
substituting x = 4 in -6 < -2x
-6 < -2x
-6 < -2(4)
-6 < -8
FALSE!
Thus, x = 4 does not satisfiy the inequality -6 < -2x
∴ x = 4 is the NOT a solution to the inequality -6 < -2x.
Conclusion:
x = 4 is NOT a solution to both inequalites.
Part c) Find another value of x that is a solution to both inequalities.
solving -2x < 10
[tex]-2x\:<\:10[/tex]
Multiply both sides by -1 (reverses the inequality)
[tex]\left(-2x\right)\left(-1\right)>10\left(-1\right)[/tex]
Simplify
[tex]2x>-10[/tex]
Divide both sides by 2
[tex]\frac{2x}{2}>\frac{-10}{2}[/tex]
[tex]x>-5[/tex]
[tex]-2x<10\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x>-5\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-5,\:\infty \:\right)\end{bmatrix}[/tex]
solving -6 < -2x
-6 < -2x
switch sides
[tex]-2x>-6[/tex]
Multiply both sides by -1 (reverses the inequality)
[tex]\left(-2x\right)\left(-1\right)<\left(-6\right)\left(-1\right)[/tex]
Simplify
[tex]2x<6[/tex]
Divide both sides by 2
[tex]\frac{2x}{2}<\frac{6}{2}[/tex]
[tex]x<3[/tex]
[tex]-6<-2x\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x<3\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:3\right)\end{bmatrix}[/tex]
Thus, the two intervals:
[tex]\left(-\infty \:,\:3\right)[/tex]
[tex]\left(-5,\:\infty \:\right)[/tex]
The intersection of these two intervals would be the solution to both inequalities.
[tex]\left(-\infty \:,\:3\right)[/tex] and [tex]\left(-5,\:\infty \:\right)[/tex]
As x = 1 is included in both intervals.
so x = 1 would be another solution common to both inequalities.
SUBSTITUTING x = 1FOR -2x < 10
substituting x = 1 in -2x < 10
-2x < 10
-3(1) < 10
-3 < 10
TRUE!
Thus, x = 1 satisfies the inequality -2x < 10.
∴ x = 1 is the solution to the inequality -2x < 10.
FOR -6 < -2x
substituting x = 1 in -6 < -2x
-6 < -2x
-6 < -2(1)
-6 < -2
TRUE!
Thus, x = 1 satisfies the inequality -6 < -2x
∴ x = 1 is the solution to the inequality -6 < -2x.
Conclusion:
x = 1 is a solution common to both inequalites.

Suppose y varies directly with x. If y = 4 when x = 0.4, what is y when x is 5?
Step-by-step explanation:
y = kx, where k is a real constant.
When x = 0.4, y = 4.
=> (4) = (0.4)k, k = 10.
Hence when x = 5,
y = kx = (10)(5) = 50.
The answer is 50.
